VAULT-DOOR LOCK.

To all whom it may concern:

Be it known that I, JOHN STnvnNs, a citizen of the United States,residlng at Galion, in the county of Crawford and State of Ohio, haveinvented certain new and useful Improvements in Vault-Door Locks, ofwhich the following is a specification.

My invention relates to looks for covers for vaults, safes, safetydeposit boxes and the like and its object is to provide a cover that maybe permanently locked to the casing of the vault or the like againstremoval from the exterior of the casing or one side thereof.

The invention relates in the details of construction and arrangements ofthe parts of the device described hereinafter and illustrated in theaccompanying drawings.

Said drawings illustrate the preferred embodiment, and therein Figure 1,is a plan view; Fig. 2, is a horizontal sectional view through a vaultor the like showing the same inverted and its cover in inverted plan;Fig. 3, is a cross section on line 33 of Fig. 2; Fig. 4, is a detallshowing the head and wedge plate in unlocked position; Fig. 5, is adetail sectlon show ng the head and associated parts in position forturning or movement to locked position, and Fig. 6, is a detail sectionon the line 55 of Fig. 2.

Throughout the drawings like reference characters designate like orcorresponding parts throughout the views thereof.

Referring specifically to the drawings, 1

is a casing or body of a'vault, receptacle or i the like shown as havingits rim extending inwardly to provide a continuous angle flange 2 at itsopening. The opening at the flange is spanned by a cover 3. A stem 4 ismounted for sliding movement transversely of the cover and for turningmovement in openings in the cover and in a bolt shifting plate 5, thelatter arranged lnteriorly of the vault structure. From the plate extendoutwardly a suitable numberof properly shaped bolts 6, the same beingp1votally mounted on the plate as by means of fastening bolts or members7. Auxiliary bolts 8 may be bolted or otherwise pivoted as 9 to the bolt6. Suitable guide devices 10 for the bolts 6 and 8 are preferablyemployed having suitable enlarged openings through which the bolts passand sultably fastened as by bolts at 11-to the cover 3. On the plate 5is formed an offset, substan- Specificati on of Letters Patent. Patent dD 29 1914 Application filed December 18, 1913. Serial N 0. 807,484.

tially U-shaped frame 12 having an open end providing a slot to receivea wedge plate and a head now to be described, at suitable times. A wedgeplate 13, is employed, having a bifurcated or forked end providing aslot 14' adapted to receive the stem as seen in Fig. 2. This wedge iscarried by a spring wire 13 secured to plate 5. The slidable stem 4 hasfastened to its inner end a head 14, shown as square to correspond tothe shape of the recess defined by frame 12. Frame 12 forms an abutmentfor the head 14 upon turning of the stem 4, and the stem 4 in oneposition forms an abutment for frame 12; thus insuring movement of boththe frame and stem upon movement of the stem. A latch15 is employed toengage a notch 16 in the periphery of the plate 5 and is slidinglymounted in the brackets 17 and carried by a spring 18 fastened to thecover 3. For a purpose later to be explained the stem 4 may be providedwith a slot or aperture 19, to removably receive a pin 20. Stem 4 hasexterior of the casing an operating or tool engaging head 21. I

When the cover is fastened as seen in Fig. 2, the same rests upon theexterior of flange 2, and the bolts 6 and 8 engaged against the interiorthereof, effecting the locking of the cover. When thus locked latch 15engages in slot 16, and wedge 13 is in the recess of I the frame 12 andhead 14 is so positioned, as seen inFig. 3, that turning thereof by themanipulation of a suitable tool at head 21, will turn the same beyondthe frame and thus not disturb the locking relation of the parts. Itwill thus be seen that the cover cannot be removed from the exteriorwithout destruction of the vault. The cover may thus serve eliicientlyin connection with a vault employing a door or closure member operablefor unlocking from the interior of the vault, and may also serveefficiently in connection with a vault used for temporary burial ofmoney or valuables. The bolts 6 and 8 are slidingly mounted but beforeplacing the cover onto the vault casing the stem through slidingmovement is moved outwardly so that the head 14 will extend into therecess of frame 12 as seen in Fig. 5, in which position the parts may befastened by means of the key or pin so extending through the slot 19.Accordingly when the stem is turned in the proper direction forretraction of the bolts they are moved to position permitting theplacing of the cover 3 onto the casing. /Vhen thus placed latch 15 isout of engagement with the notch 16 and the wedge 13 bears against theframe 12 or head 14, the latter feature being shown in Fig. 4. Afterthus positioning the cover the stem is turned in the proper direction toslide or throw the bolt to the locking position shown in Fig. 2. vVhenthis position is reached, latch 15 enters notch 16 and arrests movementsof the parts, resisting normal turning movements imparted thereto. Atthis time the wedge 13 is opposite the slot of frame 12. Pin 20, ifemployed, is then removed and the stem 4 pressed inwardly whereupon thehead M is moved out of the slot and the spring 13 moves the wedge 13thereinto. Thus the stem is locked against further sliding and turningof the stem thereafter will result in turning of the same alone withoutdisturbing the relation of the locked parts. If access is afterward hadto the interior of the vault, the vault is broken for that purpose, butif the interior of the vault is accessible otherwise than throu 'h theopening at the cover, latch 15 and wedges 13 are moved from lookingposition and stem 4 is thereupon properly adjusted to retract the boltsso that the cover can be removed.

As merely the preferred embodiment has been illustrated and described itis to be understood that changes such as fall within the spirit andscope of the appended claims are reserved.

Having thus described my said invention what I claim as new and desireto secure by Letters Patent is:

1. In a device of the class described, a cover, a stem slidable in aplane substantially at right angles to the cover, a plate turnable attimes with said stem, said stem cotiperating with said plate and cover,and means operable through movement of the plate to lock said stemagainst sliding movement, for the purpose specified.

2. In a device of the class described, a cover, a movable plate, arotatable stem slidable transversely of said plate and cover and a wedgemember operable through movement of the plate to lock said stem againstsliding movement.

In a device of the class described, a cover, a plate provided with aslot, a stem slidable transversely of said cover and plate and having ahead thereon engageable with said slot and a wedge associated with saidparts to enter said slot and lock said stem against sliding movement.

4. In a device of the class described, a cover, a turnable plate, a stemslidable transversely of the cover and plate, means to arrest movementof said plate and maintain plate against movement, and means to locksaid stem against sliding movement operating automatically upon thearrest of movement of the plate, for the purpose specified.

5. In a device of the class described, cover, a turnable plate, boltscarried by said plate, a rotatable stem slidable transversely of thecover and plate, a head on said stem, said plate provided with abutmentmeans engageable by said head, and a wedge engageable intermediate saidplate and head to lock said stem against sliding movement to engage saidabutment means.

6. In a device of the class described, cover, a turnable plate, arotatable stem slidable transversely of the cover and plate, an abutmentmember on said plate, an abutment member on said stem engageable withsaid abutment member of the plate, and means to fasten said stem inposition preventing abutment of said abutment members with each other.

7. In a device of the class described, a cover, a turnable plate, arotatable stem slidable transversely of the cover and plate, a latch forsaid plate, bolts, an abutment member on said plate, an abutment memberon said stem engageable with the first mentioned abutment member, awedge, a spring associated therewith, said wedge adapted to lock saidstem to prevent abutting engagement of said abutment members with eachother.

In testimony whereof I afliX my signature in presence of two witnesses.
